V -O-P-P- The Schedule referred to in the otters Patent and making part o! the name To all wltom itmay concern: l

Beit known that I, ALFRED G. SAFFORD,'of St.n Albans, in the county of Franklin, and State of Ver-` 1nont,'have invented a new and improved '-Method of lnsulating Air-Telegraph Lines; and I do hereby dcclare that the following is a full and .exact description f thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a. part of this specification.

The nature of my invention consists in' providing telegraph-insulators, as now used, with aforked hook and a conical cap or covering, which said cap or covering shall prevent the difficulties arising from the loss of the electric current, by means of the dampness adheling to said insulators', duringstorms, or=from the condensation of humid atmosphere.

A flo enable those skilledn the art to make and use my invention, I will'proceed to describe'its construe tion audopemtion.

' I construct the pole or cross-bar in the usual man-1` ner, and can use the ordinary barrel-insulator, Figure 1, orany non-conductor; but in order to obviatc the' dificulties arising from the loss of the electn'c current, hy means ofthe adhesion of dampuess during storms, or theresults of condensation, I construct the hook A, Figure 2, and by means thereof carry the point of attachment of' the conducting-wire below the top .of th'e pole or'cross-bar; and 'I also construct the. con ical cap or covering B, Figure 3, with a uted aperture, C, flanged at 1), and with the supports E E E,

and fasten thcsame over the insulator, Figure 4.

AThe shape of the hook and the conical cap will, of course, vary with the position and .shapel of thc insulater to be protected.-

When the atmosphere becomes damp, either from storms or vapors, the moisture arising from the storms is calriedolon the outer surface of the cap,while that resulting from the condensation of humid titulospherc between the cap and the insulator will exhibit itself on, and is carried ofi' by the inner surface ofthe cap through the apertures between the cap andf the top of the pole, thereby securing dryness in every state of the atmosphere, as well for the insulator the top of the pole, preventing the loss-,of the current upon the wire otherwise resulting. g i

Having thus described my invent-ion,

I claim therein as new, and desire to secure'by Letters Patentv Extended covering-capsB, in combination with the insulators` of air-line telegraphs, when said caps are so forlnedandsecured as to cover and. fully enclose'the insulators independently thereof, substantially as and' 'for the purpose herein set forth.

- Also, a line-supporting hook, A, combined with and dependent from a banni-insulator, substantially as and for the purpose herein set forth.
